Front sight adjustment.

[Tgc]

Gentlemen. I managed to actually go shooting shooting a couple of weeks back. I was shooting my CPA 45 70. The bullet impacts were to the left, 2.375" at 100 yards. The mild breeze was left to right. I had the rear sight at '0' windage. To move the bullet impact to the right, I need to move the front sight to the left. The target distance was 100 yards, or 3600 inches. My sight radius is 33". I divided 3600" ÷33" =109.09. 2.375" ÷109.09=.02177. I moved the front sight .022 to the left. Is my thinking correct? Or will I get a big surprise next time I shoot? Thanks. Tim
